CAR-COUPLING.

SPECIFICATION forming part. of Letters Patent No. 549,633, dated November 12, 1895. Application tiled September 16, 1896. Serial No. 562,665. (No modeld To all wit-0111, it nmg concern:

lie it known that I, HUGH DONLEY, of Cannelton, iii-the county of Beaver and State of Pennsylvania, have invented an Improved Car-Coupler, of which the following is a specification. 'l, his ,4 invention relates,generally, to car- (fOil[)l( il'S,zlll l part icula rly to that class thereof known as the .lanney type; and the objects of this invention are, first, to provide an improved form of. pinoperating mechanism; secondly, to provide improved means for a utomatically throwing the knuckle outward when the pin is raised to unlock said knuckle. With these objects in view the invention consists in the peculiar construction of the several parts and the novel manner of combining or arranging the1n,such as will be fully described hereinafter, and then pointed out in the claims.

In the drawings forming a part of this specification, Figure l a perspective view of a car-coupler embodying my invention. Fig. 2 is a vertical longitudinal section. Fig. 3 is a horizontal longitudinal section. Fig. i is av sectional view on the line i t of Fig. I Fig. 5 is a detail perspective. view of the knuckle. Fig 6 is a detail perspective view ol the pin, and Fig. 7 is a detail perspective view of the lever operated by the pin to open the knuckle. In carrying out my invention I employ the draw-head A, which in general contour is substantially the "same as the draw-head of the ordinary Janneycoupler-tlmt is,it comprises the rigid ,jaw 14 and the movable knuckle a. The movable knuckle (1, is provided, as usual, with the iiiwaidly-extendingarm ll,which is adapted to be engaged hythe vertical sliding pin for the pn rpose of locking said knuckle, and in connection with said knuckle and pin I provide aknuckle-opening lever i), which is pivoted within the d raw-head to one side of the arm I1 and operated by the upward movement of the locking-pin,so that. when said pin is raised to unlock the knuckle said lever will be operated by said pin. to throw the knuckle open. The pin, \vh ich most clearly illustrated in Fig. 7, is the square upper portion 0 and the flat; narrowportion c", said upper portion terminating in a sl1oulder6-,which is cut away at; for the purpose of permitting the end of the arm 1} to-pa-ss through beneath,

said arm being beveled orcut away, as shown at 1:, which engages the cut-away port ion r".

and automatically raises the pin until said arm has passed beyond the shoulder, when said pin is dropped bygravitvaud automaiica-lly locks the knuckle.

grooved upon its upper and lower l'accs near the f0l'Wi(l(l end, as shown zit-1:, which grooves The arm I; is also receive the guides IF, formed in the draw-v I bar said lever being ivoted u )0 a rod or bolt E, passing transvm-sclv through said draw-head, the forward end, olf said lever working in a mortise ("in the pin, and the rear end of said lever is pivotallv connected .to asee'ond lever l, which is also located in the draw-bar, fulcrumed upon a rod or shaft f, and the forward end ol? said lcvcr projects into the draw-head alongside ot' the pin and rests upon a 'lug or linger g of the vertical moving lifting-rod (4, which slides in a vertical groove By means of the abovc-dcscriln-d .constrnction it will be readilvsecn that h vraisingtho lifting-rod the lever 1." will he raised at its forward end and drops at its rear end, and inasmuch as this lever l is connected at its rearend to the rear end oli the lever E the forward end oli said. lever E will he raised. and with. it; the pin t.

Now in order toopcn the knuckle automaticallv at the. same time the pin rclmlscs it, I employ a luluckle-ojnuiing lever .l), before referred to, which is pivoted within aroeess formed in the side ol? the draw-hczul,

and by referring to Fig. '7 it will. be seen that said lever comprises a l'orwardl v-curved nut; d and lug d at the rear end, which lug has acurved oibeveled l'a-ce d for a purpose presently described, and the. enlarged port ion (1, through. which the pivotal bolt passes. in order to pivotally secure said lcvcr wit hin. the recess in the draw-head. The pin 0 is formed with a curved or slop-' ing edge 0", which engages the curved or beveled face (7, of the lug II, so'that as said pin is raised the curved surfaces will engage each other, the rearend ot' the knuckle-opening lever-rod forced inward and the forward end thrown outward, and as said rod seats, in a recess a, formed in the knuckle, said knuckle will be thrown open and the car will be ready for eouplin In order to render the operation of the lever quicker and easier, l form the knuckle with a curved boss aflwhieh contacts with a curved portion (Z of the knuckle-openi ng' lever, whereby t he purchase or bearing surface between the knuckle and lever is increased.

In order to permit. the insertion of the peculiar-shaped pin the draw-head is const rnct ed with a siniilarly-shaped opening, and in order to close the said opening at the upper end. I employ a cap-piece or block Ii, which is held in place by apivotal bolt of the knuckleopening lever and completely covers the opening in the drmv-hea-d; and I further utilize this block or cap-piece and make it actas a stop for the pin byplacing a horizontal lug or finger hin the side of the pin t, which lug or finger engages the bottom of the cap-piece or block ll, and thus limits the upward movementof the pin C.

By means of the peculiar arrangement of thclevers E and F located in the shoulder, the movement of the pin is rendered quick and certain, and the quickness of said pin serves to positively actuate the knuckle-openin g lever, so that it will be seen that I provide a car-coupling embodying these automatic features, which will operate in a wholly cilicient andflsatisfactory manner.

Havingthus described my invention, what I. claim a'snenxand desireto secure by Letters Patent,

I. In a coupling of the class described, the combination, with the d raw-head, and knuckle, ot' the eouplin; pin, the operat ingleve'rs arranged within the draw-bu r, and the lifting rod for operating said levers, substantially as shown and described.

9. In a coupling; of the class described, the combination with the drmv-banztnd head, and knuckle, olf the coupling pin, the levers E, and F, arranged within the draw-bar, and the lifting rod G, for operating the said levers, substantially as shown and. described.

3. In a coupling of the class described, the combi nat ion,with the d raw-heathot the knuckle, having the rear end of its locking arm beveled or-curved, and a recess or seat upon the inner face of said locking arm, andthe boss or enlargement adjacent to said recess or seat, the uncoupling lever having a curved forward end, and the beveled lug at the rear end, and the coupling, pin having a square upper end, a flat lower end with intermediate locking shoulder, an inclined. operating surface, said locking shoulderadapted to engage the locking arm of the knuckle, and the inclined surface being adapted to engage the beveled or curved lug of the opening lever, substantially as shown and described.

4. In a coupling of the class deseri bed, the combination, with a coupling pin, having square upper end, and flat lower portions'ot' the cap'orbloek ll, and the lug or finger 7:, all arranged and adapt-ed to operate substantially as shown and described.

In testimonywhereof I attix my signature in the presence of. two witnesses.
